This is a division of application Ser. No. 279,971, filed Aug. 11, 1972.

The compounds according to the invention have interestingpharmacological properties. They have in particular a very strongcentral activity which may be expressed both in an anti-depressiveactivity, whether or not caused by monoamino oxidase inhibition, and ina sedative or anticonvulsive activity.

In particular those compounds according to the invention in which bothR₁ and R₂ represent a hydrogen atom have a strong activity.

The monoamino oxidase inhibiting effect of compounds of formula I wasfound in experiments in which a quantity of the compound to be testedwas administered intraperitoneally or orally to five male albino mice.One hour after the administration the animals were injectedsubcutaneously with tryptamine hydrochloride in a quantity of 250mgms/kgm. This quantity caused no mortality in animals which had notreceived the compound to be tested but dis cause mortality in theanimals which had been treated. Eighteen hours after the administrationof tryptamine hydrchloride it was determined how many treated animalshad died. The ED₅₀ was determined from the results.

The antidepressive effect of compounds of formula I was also determinedin the tetrabenazine test. In this test a quantity of the compound to betested was administered intraperitoneally or orally to five male albinomice. After 45 minutes the animals were injected subcutaneously with 80mgms per kgm of tetrabenazine. After another 45 minutes the degree ofptosis was determined and compared with the ptosis of animals which hadreceived tetrabenazine alone. The ED₅₀ was determined from the results.

The sedative effect of compounds according to the invention was found inthe hexobarbital narcotising test. In this test a compound to be testedwas administered intraperitoneally and orally, respectively, 60 minutesprior to a dose of hexobarbital (30 mgms/kgm) which was just less thannarcotic. Induction of narcosis was the criterion for the activity ofthe substance. The ED₅₀ was calculated from a series of experiments withvarying dosages.

The anticonvulsive effect of compounds according to the inventionagainst superamaximal electric shock was determined in female mice 30minutes after an intraperitoneal administration or 60 minutes after anoral administration of the compound to be tested.

The influence of compounds on the convulsive effect of a supramaximalintravenously administered dose of pentamethylene tetrazol (50 mgms/kgm)was also determined in female mice 30 minutes after an intraperitonealadministration or 60 minutes after an oral administration of a compound.

The antidepressive compounds according to the invention are particularlysuitable for use in the therapy of neurotic and psychotic disturbances,in particular of the depressive syndrome and also for the treatment ofpsychosomatic disturbances. The substances may therefore be administeredto depressive patients as a psychostimulant.

The sedative compounds are excellently suitable for use as an ataractic.They may successfully be used for the treatment of mild psychoneuroticphenomena.

The anti-convulsive compounds may be used in the treatment of epilepticpatients.

The cmpounds, including the HCl salt of O-(2-amino-ethyl)2,6-dichlorobenzaldoxim, may be administered in the conventional mannersafter having been brought in a suitable form of administration. They maybe injected or be administered orally or rectally. As forms ofadministration are therefore to be considered inter alia: injectionliquids, pills, tablets, coated tablets, capsules, powders, and thelike.

The way in which, the quantity in which and the frequency with which thesubstances are to be administered to the patient may vary for eachindividual patient also in accordance with the severity of thedisturbances. In general, the practitioner will have no trouble inchoosing the correct therapy for a given patient.

The dosing of sedative and antidepressive compounds will in general befrom 10 to 500 mgms daily for adults. As a rule a quantity of from 10 to150 mgms will be sufficient.

Anti-convulsives according to the invention will generally beadministered in dosages of from 100 to 500 mgms daily.

The compounds according to the invention, including the HCl salt of0-(2-aminoethyl)2,6-dichlorobenzaldoxim may be processed according tomethods commonly used in pharmacy to compositions, for example, bymixing an active substance with or dissolving it in solid or liquidcarriers.

As such are to be considered the conventional carriers, for example,water made isotonic with blood, if desired, for example, by means ofkitchen salt, glycerin, chalk, calcium phosphate, lactose, powderedsugar, calcium carbonate. As swelling agents in tablets and coatedtablets may be used, for example, potato starch, maize starch, arrowroot (amylum marantae), carboxy methylcellulose, gelatin and acacia gum.

As lubricants may be used talcum, magnesium stearate, calcium stearate,and stearic acid. Compositions for oral administration may contain inaddition flavouring substances, for example, sugars or vanilla extract.

As preservatives may be used, for example, propyl-p-hydroxy-benzoate andbenzyl alcohol. The compositions may contain in addition surface-activesubstances, for example, mono-, di- and tri-esters of higher fattyacids.

As examples of pharmaceutically acceptable acids with which thecompounds can form salts may be mentioned: hydrohalogenic acids, forexample, hydrochloric acid, hydrobromic acid, in addition otherinorganic acids, for example, sulphuric acid, nitric acid, phosphoricacid, and organic acids, for example, citric acid, acetic acid, oxalicacid, fumaric acid, lactic acid, succinic acid, sulphamic acid, benzoicacid, tartaric acid, gallic acid.

The compounds according to the invention may be prepared according tomethods which are known per se.

The invention therefore also relates to a method of preparing new oximethers, characterized in that compounds of formula I ##SPC2##

and salts thereof with pharmaceutically acceptable acids, in whichformula all the substituents may be hydrogen while R₁ and R₂ mayfurthermore represent a methyl group, R₃ an alkyl group, analkoxyalkylene group, an alkylthioalkylene group, analkylsulphoxyalkylene group, an alkylsulphonalkylene group having up to8 carbon atoms or a benzyl group, and R₄, R₅ and R₆ may each be ahalogen atom, an alkyl group, an alkoxy group or an alkylthio grouphaving up to 6 carbon atoms, a benzyloxy group, a hydroxy group, anamino group, an alkylamino group or a dialkylamino group, in which theakyl group(s) contain(s) 1 or 2 carbon atoms, a nitrile group or atrifluoromethyl group and two of the substituents R₄, R₅ and R₆ may eachbe a meta nitro group or together a trimethylene group, a tetramethylenegroup, a methylenedioxy group, an ethylenedioxy group, a benzo group, apyridino group, an indeno-1,2 group, a 1,4-benzthiazino-2,3 group or a1,4-benzoxthiino-2,3 group, with the exception of the HCl salt of thecompound in which R₅ and R₆ each represent an orthochlorine atom and R₁,R₂, R₃ and R₄ each represent a hydrogen atom, are prepared according tomethods which are known for the preparation of this type of compoundsand according to methods analogous thereto.

For example, compounds according to the invention may be prepared byreacting a compound of formula II ##SPC3##

wherein M is a hydrogen atom or an alkali metal atom, with a compound offormula III ##EQU1## wherein X is a halogen atom, preferably a bromineor chlorine atom or a tosyloxy group and Y is a hydrogen atom or an acylgroup, for example, an alkoxycarbonyl group or a carbobenzoxy group,which, after the coupling reaction, is split off by hydrolysis.

The reaction may be carried out in a suitable solvent. As such are to beconsidered inter alia: alcohols, for example, methanol, ethanol,ketones, for example, acetone and methylethyl ketone, and ethers, forexample, dioxane, dimethylglycol ether.

When M in formula II is a hydrogen atom, it may be recommendable to addan acid binder to the reaction mixture. As such may be mentioned interalia alcoholates, potassium carbonate and sodium carbonate, tertiaryamines, pyridine and the like.

The temperature of the reaction mixture may vary between rather widelimits. As a rule, however, it will be between 0° and 50°C.

The oxims of formula II may be obtained in the conventional manner fromthe corresponding aldehydes or ketones by means of hydroxylamine. Theoximates may be prepared from the oxims by adding the oxims, whether ornot dissolved in alcohol, to a solution of potassium or sodiumalcoholate or -hydroxide in alcohol.

The compounds according to the invention may alternatively be obtainedby reacting a compound of formula IV ##SPC4##

with a compound of formula V ##EQU2## wherein Y is a hydrogen atom, oran acylgroup for example an alkoxycarbonyl group or a carbobenzoxy groupwhich, after the coupling reaction, is split off by hydrolysis.

The reaction may be carried out in a suitable solent. As such may bementioned: alcohols, pyridine, dioxane, dimethylformamide,tetrahydrofurane and the like or mixtures thereof. In general thereaction temperature lies between room temperature and the boiling pointof the solvent. An alternative method of preparing compounds accordingto the invention is that in which an oxim of formula II (M = H) isreacted with an imine of the formula VI ##EQU3## wherein R'₁ is an acylgroup which is split off after the reaction by hydrolysis.

The reaction may be carried out in a suitable solvent, for example,dioxane, benzene.

The compounds according to the invention may also be obtained byreacting a compound of formula VII ##SPC5##

wherein X is a halogen atom, preferably a bromine atom or a tosyloxygroup, with ammonia or methylamine.

The reaction may be carried out, for example, in alcohols.

The starting substances of formula VII may be obtained by reacting oximsof formula II (M = H) in the presence of an acid binder with a halogencompound of formula VIII ##EQU4## wherein X has the same meaning as informula VII and Hal is a halogen atom, preferably a bromine atom. Whenin formula II one or more of the substituents R₄, R₅ and R₆ is a primaryor secondary amino group and a hydroxy group, respectively, it ispreferably protected with an acyl group and a benzyl group,respectively, which groups are subsequently split off by hydrolysis orhydrogenolysis.
